彩色多普勒超声评价颈动脉粥样硬化与冠心病的关系

目的探究彩色多普勒超声评价颈动脉粥样硬化与冠心病(CHD)的关系。方法选取于我院确诊的91例CHD患者为CHD组,另外选取同期于我院进行体检的健康者27例为健康组,给予两组研究对象彩色多普勒超声检查。比较两组不同测量位点的颈动脉内中膜厚度(IMT)、颈动脉粥样硬化斑块情况及不同冠状动脉支数的CHD组患者与健康组患者的造影图像参数,并分析CHD患者的颈总动脉IMT与冠脉病变程度的相关性。结果CHD组LCCA、LICA、LECA、LB、RCCA、RICA、RECA、RB测量位点的IMT均大于健康组(P<0.05)。CHD组颈动脉粥样硬化斑块总发生率高于健康组,且两组的斑块分型有显著差异(P<0.05)。单支冠脉异常组、多支冠脉异常组及健康组的TTP、IMAX%、AUC均有显著差异(P<0.05)。91例CHD患者的平均Gensini评分与IMT呈正相关(r=0.617,P<0.05)。结论颈动脉粥样硬化与CHD相关,且CHD可通过彩色多普勒超声准确判断。

Evaluation of the relationship between carotid atherosclerosis and coronary heart disease by color Doppler ultrasound

Objective To explore the relationship between carotid atherosclerosis and coronary heart disease(CHD)evaluated by color Doppler ultrasound.Methods A total of 91 patients with CHD diagnosed in our hospital were selected as CHD group,and 27 healthy person who had physical examination in our hospital at the same time were selected as healthy group,and the two groups were given color Doppler ultrasound examination.The intima-media thickness(IMT)at different measurement sites,carotid atherosclerotic plaque and angiographic parameters of the CHD group patients with different coronary artery counts and the healthy group patients were compared,and the correlation between IMT of arteria carotis communis and the degree of coronary lesions in CHD patients was analyzed.Results IMT at measurement sites of LCCA,LICA,LECA,LB,RCCA,RICA,RECA and RB in the CHD group were greater than those in the healthy group(P<0.05).The total incidence of carotid atherosclerotic plaque in the CHD group was higher than that in the healthy group,and there was a significant difference in plaque type between the two groups(P<0.05).There were significant differences in TTP,IMAX%and AUC among the single-vessel coronary anomaly group,the multi-vessel coronary anomaly group and the healthy group(P<0.05).The average Gensini score of 91 patients with CHD was positively correlated with IMT(r=0.617,P<0.05).Conclusion Carotid atherosclerosis is associated with CHD,and CHD can be accurately determined by color doppler ultrasound.
